Having just finished a large amount of work in Litho (frozen peas and such),
I would advise that you do not put any white backing under your material.
However, leaving the black did not always give the results I wanted either.
Although I know it's not standard method, and many may pick the technique
apart, I had success with putting a neutral gray under the polyethelene. The
visual appearance of the final product was better this way for some reason.
I would also recommend that you measure with a gretag spectrolino with the
UV filter on or an X-Rite SP-64.
